How to play
- Move up, down, left or right: every number slides that way.
- When two equal numbers meet, they merge into one number twice as large (2 + 2 = 4, 4 + 4 = 8). A merged number never merges again in the same move.
- After every move, a new 2 (sometimes a 4) appears in an empty cell. If nothing moved, nothing appears.
- Make 2048 to clear the game, then keep going for even bigger numbers.
- The game ends when no move is possible in any direction.
Every merged number is added to your score (making a 4 scores 4 points).

Saving
The current board, your score, your best score and whether you reached 2048 are stored only in this browser's localStorage (picochest.play.cat-number-merge.v1), so you can continue where you left off next time. Nothing is sent to PicoChest's servers, and nothing carries over to another device or browser. Clearing your browser data deletes it. See the Privacy Policy for details.
